Desarrollo de un balanceado no tradicional con tres niveles de proteína vegetal para el crecimiento de la tilapia roja (Oreochromis sp.)

Abstract

The objective of this investigation was to develop a nontraditional balanced feed with three levels of vegetable protein for the growth of red tilapia (Oreochromis sp.) In order to minimize costs and satisfy the excessive demand of fishmeal. Being able to create a substitute as a protein source in the balanced aquaculture. The quinoa flours, the soy flour and the chickpea flour were all used as base ingredients, which were elaborated and analyzed in order to comply with the norms established by the INEN. For the design of mixtures the statistical program “Desing expert 11.0” was used; it was established 11 formulations and then analyzed in the different treatments.The formulations selected by the program determined that none of those that were used was equal to or better than the formula of the sample because the weights, sizes, mortality, and the feed conversion had no benefits beside the common balanced. Resulting in the acceptance of the null hypothesis which confirms that the balanced feed proposed in the present project will not allow improving the fattening indicators of the red tilapia (Oreochromis sp) which is basically the most important variable in aquaculture production.
